Hydroelectric

Source: Running Water

Hydroelectricity is converted into energy by using kinetic energy of the moving water to make electricity. The water goes through a tunnel and moves and turns the turbines powering generators inside that makes power and that power is cheap and can be used to power houses and factories.

Today hydroelectricity is used to power factories and homes near dams. Dams produce this energy with moving water.


Advantages

1. Electricity can be generated constantly
2. Once the dam is built the energy is virtually free
3. No waste or pollution produced
4. Much more reliable than wind, solar or wave power
5. Water can be stored above

Disadvantages

1. Water quality and quantity downstream can be affected, which can have an impactedon plant life
2. The dams are expensive to build
3. Finding a suitable site can be difficult
